Respectively use the original NC code and the compensated NC code in the blade surface finish machining, then collect the points data of the blade surface with a coordinate measuring machine.

分别用原nc代码及补偿后的NC代码进行叶片型面的精加工，接着用三坐标测量机进行加工表面点数据的采集。

Firstly, it produces a superior surface finish with all machining marks being removed from the surface.

首先，它通过去除所有机加工痕迹能产生较好的表面光洁度。
